Patent attributes
An adjustable-frequency two-element bowtie antenna includes a support member on which first and second non-conductive hollow element support arms are mounted. Each support arm includes first and second opposing segments. The first and second segments of each element support arm include a first section extending outwardly from the support member, a curved transition section, and a second section extending in a direction towards and joining the second section of the other element support arm. The spacing between the first sections of each segment of each element support arm increase as a function of the distance from the support member. A length-adjustable conductive member is disposed in each element support arm. Length adjusters are coupled to the conductive members to configure the lengths of antenna elements. A connector may be provided to couple a transmission-line to a pair of the conductive members comprising a driven element.
